Amusing tension spoke wheel model
Here's a simple demo of how a bicycle wheel works. Some may find it
amusing. Take a short axle (I used a piece of PVC pipe) and put it in a vise, end up. Drop four reasonably matched rubber bands over the axle. I used bands from the morning paper, rather thin. Place a ring about twice the diameter of the bands on top. I used a large keyring. Helps if the ring isn't too slippery. Pull the rubber bands over the edge of the ring, and over the axle. It's easy if the axle is held securely, thus the vise. Shift the rubber bands until the ring is roughly centered. Now you have a model bicycle wheel and can explore its behavior. The most notable features are its radial stiffness and axial compliance. With a large(ish) axle it's fairly stiff torsionally. Thanks for reading, bob prohaska |

You have a lot of nerve using rec.bicycles.tech for something technical about bicycles. |
